This child item contains the spatial data associated with the bathymetric survey of the Levittown lake, conducted on January 11, 2011. The child item consist of two datasets: 1) contours of the lake bottom and 2) data points colleced along each established navigation line, to calculate the water volume of the lake at mean sea level. A bathymetric/land survey system (BLASS) interfaced to a depth sounder was used to conduct the survey. The system consists of a Global Positioning System (GPS) and a digital depth sounder. Geographic location and water depth data were simultaneously collected and stored in a portable computer. The data were then transferred into the USGS geographic information system (GIS) for processing...
Data for the Hydrologic and Water-Quality Characterization of Levittown Lake, Toa Baja, Puerto Rico, April 2010 – June 2011
This data release contains data for the hydrologic and water-quality characterization of Levittown Lake, from April 2010 to June 2021. Three child items were included in the data release to summarize the results of the (1) community productivity through the light and dark bottle method (2) two diel data collection efforts, and (3) spatial data associated with the bathymetric survey conducted at Levittown Lake to contour the lake bottom. Diel studies were conducted at the lake to estimate the community net primary productivity, the respiration rate, and the gross productivity rate. Two diel studies were conducted on November 18, 2010, and May 18, 2011, near the respective annual periods of highest and lowest tides...
Analysis of community primary productivity for the Levittown Lake, Toa Baja, Puerto Rico, November 2010 and May 2011
This dataset contains the selected physical properties and chemical constituents that were measured at Levittown Lake, Toa Baja, Puerto Rico during a diurnal cycle. Diel studies were conducted at the lake to estimate the community net primary productivity, the respiration rate, and the gross productivity rate. Two diel studies were conducted on November 18, 2010, and May 18, 2011, near the respective annual periods of highest and lowest tides for the northern coast of Puerto Rico. The community primary productivity is defined as the rate at which organic matter is created by photosynthesis and is important for supporting the food web in aquatic ecosystems. The field data collection included the measurement of physicochemical...
